Re: [Dime] [dime] #54: OC-Report-Type as mandatory AVP

[Maria Cruz Bartolome <[e-mail]>]

Hello all,

I understand JJ point of view, but I still tend to prefer to make it mandatory, since I think this is less error-prone, since the only node that knows the requested Report-Type is the reporting, if for any reason a reporting is omitting it (since it is optional), it will be always interpreted as HOST, but this type may be wrong.

I think DEFAULT values should never be error-prone, but used in "general cases", as a simplification, like e.g. a default for the Validity-Duration. Default Validity-Duration will never be an "error", it could be not the best value (compared with another value perfectly tuned to reporting node overload situation) but never the use of a Default value should lead to an erroneous behavior.

Best regards
/MCruz

I actually prefer making it mandatory. The cost of adding it is trivial--even more so for a reporting node that only supports the default. The value of having it is less opportunity for interop errors.
